CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No. 16/172,580, filed Oct. 26, 2018, the entire contents of which are incorporated herein by reference.

FIELD

Embodiments described herein relate generally to an information processing apparatus and an information processing method related to Internet Protocol (IP)-FAX communication.

BACKGROUND

IP-FAX terminals having an IP-FAX communication function are generally used. An IP-FAX terminal sends data to another IP-FAX terminal through a session initiation protocol (SIP) server when using the IP-FAX communication function. Therefore, the IP-FAX terminal needs to be registered in an SIP server.

In a large-scale network environment, there are cases of preparing a plurality of SIP servers (for example, a primary SIP server and two secondary SIP servers). The secondary SIP server serves as a preliminary device for the primary SIP server, because, even if the primary SIP server cannot operate, IP-FAX communication can be continuously performed thorough the secondary SIP server. In this case, a user may set information on the primary SIP server and the two secondary SIP servers in the IP-FAX terminal in advance. When information on the primary SIP server is correct, registration of the IP-FAX terminal with the primary SIP server is possible. When information on the secondary SIP server is correct, registration of the IP-FAX terminal with the secondary SIP server is possible.

However, the user cannot check whether settings of information on the two SIP servers are correct when settings of the information on the two SIP servers are completed, because, even if the two SIP severs are prepared, the IP-FAX terminal cannot be simultaneously registered in the two SIP servers. When the IP-FAX terminal is successfully registered in the primary SIP server, registration with the secondary SIP server is not performed. Therefore, the user cannot check whether settings of the information on the secondary SIP server are correct or not. The user may check whether settings of the information on the two SIP servers are correct by testing data transmission and reception using each of the two SIP servers. However, the workload of an operator is large.

DETAILED DESCRIPTION

According to an exemplary embodiment, an information processing apparatus includes a first display control unit and a second display control unit. The first display control unit displays a visual representation in a screen for setting a first SIP server and a second SIP server connected to an IP-FAX terminal on a display unit. The second display control unit displays a first connection state between the IP-FAX terminal and the first SIP server and a second connection state between the IP-FAX terminal and the second SIP server on the display unit, based on completion operation of setting of the first SIP server and setting of the second SIP server by a user.

Hereinafter, the present embodiment will be described using the drawings.

The configuration of an IP-FAX system 100 will now be described.

FIG. 1 is a schematic diagram illustrating the configuration of an IP-FAX system 100. An IP address is shown near each device.

The IP-FAX system 100 realizes IP-FAX communication.

The IP-FAX system 100 includes a plurality of Internet Aware FAX (IAF) devices 1-1 to 1-3, a primary SIP server 2, a secondary SIP server 3 and a personal computer 4. The devices may perform communication with each other through a network. The IP-FAX system 100 may include four or more IAF devices. The IP-FAX system 100 may include three or more SIP servers.

The IAF device 1-1 is a terminal having an IP-FAX communication function. The IAF device 1-1 may serve as IP-FAX transmitter or receiver. For example, the IAF 1-1 may be a multi-function peripheral (MFP), without being limited thereto. For example, the IAF device 1-1 transmits image data obtained from a manuscript through IP-FAX communication. The hardware configuration of the IAF device 1-1 will be described below. In addition, the IAF device 1-2 and the IAF device 1-3 are equal to the IAF device 1-1 and a description thereof will be omitted.

The primary SIP server 2 is an SIP server used for IP-FAX communication. The SIP server 2 establishes an environment in which the number of a destination is easily managed and serves as an IP-FAX exchanger. The primary SIP server 2 is preferentially used over the secondary SIP server 3. The primary SIP server 2 has a primary registrar server 21 and a primary proxy server 22.

The primary registrar server 21 is a server for registering an IAF device. In a typical example, the primary registrar server 21 registers information on an IAF device. For example, the information on the IAF device includes an SIP number and address information, without being limited thereto. For example, the SIP number may be SIP uniform resource identifier (URI). For example, the address information may be a transport address including an IP address and a port number. When the primary registrar server 21 registers the IAF device 1-1, the IAF device 1-1 may perform IP-FAX communication with another IAF device. For example, as indicated by dashed line arrow of FIG. 1, the primary registrar server 21 sends a normal response to the IAF device 1-1 based on successful registration of the IAF device 1-1. Similarly, the primary registrar server 21 sends a normal response to the IAF device 1-2 based on successful registration of the IAF device 1-2.

The primary proxy server 22 is a server for relaying IP-FAX data (packets). The primary proxy server 22 relays IP-FAX data communicated between a plurality of IAF devices registered in the primary registrar server 21. For example, as indicated by alternate long and short dash line arrow of FIG. 1, the primary registrar server 21 relays IP-FAX data from the IAF device 1-1 to the IAF device 1-2.

In addition, the primary SIP server 2 may be one server including functions of the primary registrar server 21 and the primary proxy server 22. Therefore, in the following description, the primary registrar server 21 may be appropriately replaced with the primary SIP server 2.

The secondary SIP server 3 is an SIP server used for IP-FAX communication, similarly to the primary SIP server 2. The secondary SIP server 3 has a secondary registrar server 31 and a secondary proxy server 32.

The secondary registrar server 31 is a server for registering an IAF device, similarly to the primary registrar server 21. When the secondary registrar server 31 registers the IAF device 1-1, the IAF device 1-1 may perform IP-FAX communication with another IAF device.

The secondary proxy server 32 is a server for relaying IP-FAX data (packets), similarly to the primary proxy server 22. The secondary proxy server 32 relays IP-FAX data communicated between a plurality of IAF devices registered in the secondary registrar server 31.

In addition, the secondary SIP server 3 may be one server including functions of the secondary registrar server 31 and the secondary proxy server 32. Therefore, in the following description, the secondary registrar server 31 may be appropriately replaced with the secondary SIP server 3.

The PC 4 is a terminal for performing various settings with respect to the IAF devices 1-1 to 1-3. The PC 4 performs various settings through a network by a Web service. The PC 4 is an example of an information processing apparatus.

FIG. 2 is a sequence diagram illustrating a communication operation in the IP-FAX system.

Here, an example of successfully registering the IAF device 1-1 and the IAF device 1-2 with the primary registrar server 21 will be described.

The IAF device 1-1 transmits a registration request to the primary registrar server 21. The registration request includes information necessary to register the IAF device 1-1. For example, the registration request may include information on the IAF device 1-1 of a requester and information on the primary registrar server 21 of a requestee. The information on the IAF device 1-1 may include information registered in the primary registrar server 21. The information on the primary registrar server 21 may include information used for authentication.

The primary registrar server 21 receives the registration request from the IAF device 1-1. The primary registrar server 21 performs authentication based on the registration request from the IAF device 1-1. The primary registrar server 21 registers the IAD device 1-1 based on successful authentication. The primary registrar server 21 transmits 200 OK to the IAD device 1-1 based on registration of the IAF device 1-1. 200 OK corresponds to a normal response.

The IAF device 1-1 receives 200 OK from the primary registrar server 21. The IAF device 1-1 recognizes successful registration of the IAF device 1-1 with the primary registrar server 21, based on 200 OK.

The IAF device 1-2 transmits a registration request to the primary registrar server 21, similarly to the IAF device 1-1. The primary registrar server 21 receives the registration request from the IAF device 1-2. The primary registrar server 21 performs authentication based on the registration request from the IAF device 1-2. The primary registrar server 21 registers the IAD device 1-2 based on successful authentication. The primary registrar server 21 transmits 200 OK to the IAD device 1-2 based on registration of the IAF device 1-2. The IAF device 1-2 receives 200 OK from the primary registrar server 21. The IAF device 1-2 recognizes successful registration of the IAF device 1-2 with the primary registrar server 21, based on 200 OK.

The primary registrar server 21 may register the IAF device 1-1 and the IAF device 1-2. The IAF device 1-1 and the IAF device 1-2 may communicate IP-FAX data through the primary proxy server 22.

The first registration operation and the second registration operation will be described.

FIG. 7 is a sequence diagram illustrating an example of the first registration operation and the second registration operation by the IAF device 1-1. FIG. 7 illustrates an example in which the IAF device 1-1 performs the first registration operation before the second registration operation. Assume that the first registration operation and the second registration operation are successfully executed. The IAF device 1-1 performs the first registration operation and the second registration operation under control of the processor 11 based on the operation instruction from the PC 4. The IAF device 1-1 performs the first registration operation and the second registration operation using the information set on the setting screen.

First, the IAF device 1-1 performs the first registration operation. The IAF device 1-1 transmits a registration request to the primary registrar server 21 through the communication unit 17. The registration request may include information on the IAF device 1-1 and information on the primary registrar server 21 set on the setting screen. The primary registrar server 21 receives the registration request from the IAF device 1-1. The primary registrar server 21 performs authentication based on the registration request from the IAF device 1-1. For example, assume that there is no error in the information on the primary registrar server 21 set on the setting screen. The primary registrar server 21 may register the IAF device 1-1 based on successful authentication. Meanwhile, for example, assume that there is an error in the information on the primary registrar server 21 set on the setting screen. The primary registrar server 21 may not register the IAF device 1-1 based on authentication failure. Here, the primary registrar server 21 registers the IAF device 1-1 based on successful authentication. The primary registrar server 21 transmits 200 OK to the IAF device 1-1 based on registration of the IAF device 1-1. The IAF device 1-1 receives 200 OK from the primary registrar server 21 through the communication unit 17. The IAF device 1-1 recognizes successful registration of the IAF device 1-1 with the primary registrar server 21 based on 200 OK. Successful registration of the IAF device 1-1 with the primary registrar server 21 corresponds to success of the first registration operation. Meanwhile, registration failure of the IAF device 1-1 with the primary registrar server 21 corresponds to failure of the first registration operation.

The IAF device 1-1 transmits an invalid request to the primary registrar server 21 through the communication unit 17. The invalid request is a request to invalidate registration of the IAF device 1-1 with the primary registrar server 21. The IAF device 1-1 transmits the invalid request to the primary registrar server 21, because the IAF device 1-1 cannot be simultaneously registered in a plurality of registrar servers. The primary registrar server 21 invalidates registration of the IAF device 1-1 based on the invalid request from the IAF device 1-1. The primary registrar server 21 transmits 200 OK to the IAF device 1-1 based on invalidation of registration of the IAF device 1-1. The IAF device 1-1 receives 200 OK from the primary registrar server 21 through the communication unit 17. The IAF device 1-1 recognizes invalidation of registration of the IAF device 1-1 with the primary registrar server 21 based on 200 OK.

Next, the IAF device 1-1 performs the secondary registration operation. The IAF device 1-1 transmits a registration request to the secondary registrar server 31 through the communication unit 17. The registration request may include information on the IAF device 1-1 and information on the secondary registrar server 31 set on the setting screen. The secondary registrar server 31 receives the registration request from the IAF device 1-1. The secondary registrar server 31 performs authentication based on the registration request from the IAF device 1-1. For example, assume that there is no error in the information on the secondary registrar server 31 set on the setting screen. The secondary registrar server 31 may register the IAF device 1-1 based on successful authentication. Meanwhile, for example, assume that there is an error in the information on the secondary registrar server 31 set on the setting screen. The secondary registrar server 31 may not register the IAF device 1-1 based on authentication failure. Here, the secondary registrar server 31 registers the IAF device 1-1 based on successful authentication. The secondary registrar server 31 transmits 200 OK to the IAF device 1-1 based on registration of the IAF device 1-1. The IAF device 1-1 receives 200 OK from the secondary registrar server 31 through the communication unit 17. The IAF device 1-1 recognizes successful registration of the IAF device 1-1 with secondary registrar server 31 based on 200 OK. Successful registration of the IAF device 1-1 with the secondary registrar server 31 corresponds to success of the second registration operation. Meanwhile, failure of registration of the IAF device 1-1 with the secondary registrar server 31 corresponds to failure of the secondary registration operation.

The IAF device 1-1 transmits an invalid request to the secondary registrar server 31 through the communication unit 17, because the primary SIP server 2 is more preferentially used than the secondary SIP server 3. The secondary registrar server 31 invalidates registration of the IAF device 1-1 based on the invalid request from the IAF device 1-1. The secondary registrar server 31 transmits 200 OK to the IAF device 1-1 based on invalidation of registration of the IAF device 1-1. The IAF device 1-1 receives 200 OK from the secondary registrar server through the communication unit 17. The IAF device 1-1 recognizes invalidation of registration of the IAF device 1-1 with the secondary registrar server 31 based on 200 OK.

Next, the IAF device 1-1 transmits the registration request to the primary registrar server 21 again through the communication unit 17. The primary registrar server 21 receives the registration request from the IAF device 1-1. The primary registrar server 21 performs authentication based on the registration request from the IAF device 1-1. The primary registrar server 21 registers the IAF device 1-1 based on successful authentication. The primary registrar server 21 transmits 200 OK to the IAF device 1-1 based on registration of the IAF device 1-1. The IAF device 1-1 receives 200 OK from the primary registrar server 21 through the communication unit 17. The IAF device 1-1 recognizes successful registration of the IAF device 1-1 with the primary registrar server 21 based on 200 OK.

The IAF device 1-1 is registered in the primary registrar server 21 and thus may perform IP-FAX communication with another IAF device through the primary SIP server 2.

The IAF device 1-1 transmits information indicating whether the first registration operation is successfully executed to the PC 4. The processor 41 determines whether there is an error in the information on the primary registrar server 21 set on the setting screen, depending on whether the first registration operation is successfully executed. When the first registration operation is successfully executed, the processor 41 determines that there is no error in the information on the primary registrar server 21 set on the setting screen. When the first registration operation fails, the processor 41 determines that there is an error in the information on the primary registrar server 21 set on the setting screen.

The IAF device 1-1 transmits information indicating whether the second registration operation is successfully executed to the PC 4. The processor 41 determines whether there is an error in the information on the secondary registrar server 31 set on the setting screen, depending on whether the second registration operation is successfully executed. When the second registration operation is successfully executed, the processor 41 determines that there is no error in the information on the secondary registrar server 31 set on the setting screen. When the second registration operation fails, the processor 41 determines that there is an error in the information on the secondary registrar server 31 set on the setting screen.

FIG. 8 is a sequence diagram illustrating another example of the first registration operation and the second registration operation by the IP-FAX terminal 1-1. FIG. 8 illustrates an example in which the IAF device 1-1 performs the first registration operation after the second registration operation. Assume that the first registration operation and the second registration operation are successfully executed. The IAF device 1-1 performs the first registration operation and the second registration operation under control of the processor 11 based on the operation instruction from the PC 4.

The secondary registrar server 31 performs authentication based on the registration request from the IAF device 1-1. The secondary registrar server 31 registers the IAF device 1-1 based on successful authentication. The secondary registrar server 31 transmits 200 OK to the IAF device 1-1 based on registration of the IAF device 1-1. The IAF device 1-1 receives 200 OK from the secondary registrar server 31 through the communication unit 17. The IAF device 1-1 recognizes successful registration of the IAF device 1-1 with secondary registrar server 31 based on 200 OK.

The IAF device 1-1 transmits an invalid request to the secondary registrar server 31 through the communication unit 17.

The primary registrar server 21 receives the registration request from the IAF device 1-1. The primary registrar server 21 performs authentication based on the registration request from the IAF device 1-1. The primary registrar server 21 may register the IAF device 1-1 based on successful authentication. The primary registrar server 21 transmits 200 OK to the IAF device 1-1 based on registration of the IAF device 1-1. The IAF device 1-1 receives 200 OK from the primary registrar server 21 through the communication unit 17. The IAF device 1-1 recognizes successful registration of the IAF device 1-1 with the primary registrar server 21 based on 200 OK.

The IAF device 1-1 is registered in the primary registrar server 21 and thus may perform IP-FAX communication with another IAF device through the primary SIP server 2.

The IAF device 1-1 transmits, to the PC 4, information indicating whether the first registration operation is successfully executed. The IAF device 1-1 transmits, to the PC 4, information indicating whether the second registration operation is successfully executed.

Displaying the statuses of the first connection state and the second connection state in the PC 4 will be described.

FIG. 14 is a flowchart illustrating displaying of the statuses of the first connection state and the second connection state in the PC 4. Here, the IAF device 1-1 may be used, for example.

The processor 41 registers the information on the IAF 1-1 with the primary registrar server 21 based on user operation (Act 101). Therefore, the user may acquire the information on the primary registrar server 21. The processor 41 sets the information on the primary registrar server 21 for the IAF device 1-1 based on user operation on the setting screen (Act 102). The setting screen is displayed on the display unit 46 by the first display control unit 411. When the information on the primary registrar server 21 is set (Act 103, Yes), the processor 41 processes Act 104. In Act 104, the processor 41 registers the information on the IAF 1-1 with the secondary registrar server 31 based on user operation. Therefore, the user may acquire the information on the secondary registrar server 31. The processor 41 sets the information on the secondary registrar server 31 for the IAF device 1-1 based on user operation on the setting screen (Act 105). The output unit 412 detects pressing of the save button by the user (Act 106). When the information on the primary registrar server 21 is not set (Act 103, No), the processor 41 processes Act 106.

The output unit 412 outputs the operation instruction including execution of the first registration operation and execution of the second registration operation to the IAF device 1-1 (Act 107). Therefore, the IAF device 1-1 executes the first registration operation and the second registration operation. The PC 4 receives information indicating whether the first registration operation is successfully executed from the IAF device 1-1, as a response to the operation instruction. The PC receives information indicating whether the second registration operation is successfully executed from the IAF device 1-1, as a response to the operation instruction. The second display control unit 413 determines the statuses of the first connection state and the second connection state based on the information set on the setting screen and whether the first registration operation and the second registration operation are successfully executed.

The second display control unit 413 determines whether the information on the secondary registrar server 31 is set on the setting screen (Act 108). When the information on the secondary registrar server 31 is not set (Act 108, No), the second display control unit 413 displays the status of the second connection state (Act 109). In Act 109, the second display control unit 413 displays “(blank)” on the setting screen as the status of the second connection state. When the information on the secondary registrar server 31 is set (Act 108, Yes), the second display control unit 413 determines whether the first registration operation is successfully executed (Act 110). When the first registration operation is successfully executed (Act 110, Yes), the second display control unit 413 displays the status of the first connection state (Act 111). In Act 111, the second display control unit 413 displays “registered” on the setting screen as the status of the first connection state.

The second display control unit 413 determines whether the second registration operation is success fully executed (Act 112). When the second registration operation is successfully executed (Act 112, Yes), the second display control unit 413 displays the status of the second connection state (Act 113). In Act 113, the second display control unit 413 displays “registrable” on the setting screen as the status of the second connection state. When the second registration operation fails (Act 112, No), the second display control unit 413 displays the status of the second connection state (Act 114). In Act 114, the second display control unit 413 displays “registration failure” on the setting screen as the status of the second connection state.

When the first registration fails (Act 110, No), the second display control unit 413 displays the status of the first connection state (Act 115). In Act 115, the second display control unit 413 displays “registration failure” on the setting screen as the status of the first connection state.

The second display control unit 413 determines whether the second registration operation is successfully executed (Act 116). When the second registration operation is successfully executed (Act 116, Yes), the second display control unit 413 displays the status of the second connection state (Act 117). In Act 117, the second display control unit 413 displays “registered” on the setting screen as the status of the second connection state. When the second registration operation fails (Act 116, No), the second display control unit 413 displays the status of the second connection state (Act 114). In Act 114, the second display control unit 413 displays “registration failure” on the setting screen as the status of the second connection state.

According to the present embodiment, the display 4 displays the first connection state and the second connection state on the display unit 46 based on pressing of the save button on the setting screen. Therefore, the PC 4 may provide the user with information indicating whether there is an error in the information on the registrar server set on the setting screen and whether each registrar server successfully registers the IAF 1-1. The user can easily confirm whether each registrar server successfully registers the IAF 1-1. Thus, the user can easily recognize presence/absence of errors in the information on the registrar server set on the setting screen. Since the user does not need to test data transmission and reception using each of the plurality of SIP servers in order to check whether the IAF 1-1 is successfully registered, the workload of the user is reduced.

In addition, although the PC is described as an example of the information processing apparatus in the present embodiment, the embodiment is not limited thereto. The information processing apparatus may be realized by the IAF 1-1. In this case, the IAF 1-1 includes a first display control unit, an output unit and a second display control unit installed therein. The first display control unit displays the setting screen on the display unit 16 of the IAF 1-1. The output unit outputs the operation instruction to each unit of the IAF 1-1. The second display control unit displays the first connection state and the second connection state on the display unit 16 of the IAF 1-1.
